QUESTION 21

Which of the following is not part of the logical design?

 

A.

BIOS settings

B.

Key component relationships

C.

Data flow diagrams

D.

High-level diagrams

 

Answer: A

Explanation:A logical design shows the relationship between components, without selecting specific equipment. It shows the basic flow of data between components, key component relationships, and high-level diagrams.

QUESTION 22

You are a platform designer reviewing a colleague’s design. Based on vSphere 5, the platform is designed to be scalable and provide continuous availability of the vCenter. The proposed design utilizes VMware FT.

 

Does the design meet requirements?

 

A.

Yes

B.

No

 

Answer: B

Explanation:VMware FT currently only supports 1vCPU. The vCenter requires 2vCPU and above, depending on the location of the Microsoft SQL database.

 

 

QUESTION 23

It is a best practice to give a virtual machine a single virtual CPU unless there is a compelling reason to give a virtual machine more than one virtual CPU.

 

A.

True

B.

False

 

Answer: A

Explanation:A majority of your virtual machines can run with a single vCPU. Unless the application specifically requires multiple vCPUs, try to start with one.

 

 

QUESTION 24

VMware VCAP5-DCD : Practice Test

Only a software vendor develops a standard process or configuration.

 

A.

True

B.

False

 

Answer: B

Explanation:A best practice is based on experience with delivering a solution. A new product will have limited best-practice information except for vendor- or vendor-partner-based recommendations. The longer a technology is used in a community, the more potential success; therefore, best practices may be recommended by non-vendor-related people. It is up to a designer to validate this information rather than ignore it straightaway.

QUESTION 25

For effective VMware platform validation to take place, that platform should be _____________.

 

A.

running test guest workloads

B.

running workloads of projected application resource requirements

C.

stress tested until failure to understand capacity

 

Answer: B

Explanation:A validation plan can range from a detailed test plan to high-level statements. It should not be subjective. The best validation is to place a platform under a typical test of what it will be faced with in the field –for example, having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary with the type of application and are primarily application functionality based. In addition, platform or infrastructure metrics are key for validation and for information to be used within the operational documentation (for example, troubleshooting guide, monitoring recommendations).

 

 

QUESTION 26

VMware VCAP5-DCD : Practice Test

When selecting a compute server, the architecture should use servers that are identical in every way possible, including components and the slots the components are installed in.

 

A.

True

B.

False

 

Answer: A

Explanation:Using identical servers ensures fewer issues with vMotion and aids in managing resource utilization among servers.

 

 

QUESTION 27

A vApp can be created with its own resource settings and requirements.

 

A.

True

B.

False

 

Answer: A

Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to use key management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMs to be managed by fewer staff. A vApp can have resource allocations applied at the vApp level, outside the resource pool configuration.

 

 

QUESTION 28

You are the VMware consultant at a large enterprise. A senior manager is in charge of a project that needs new infrastructure for its application. The application will be used by 3,200 users. Three virtual machines are requested via the help d

esk. One of the three is a virtual machine with 32 vCPUs allocated for processing. The notes of the request say that the large number of vCPUs (the company template is 2 vCPUs) is justified by the senior manager. The notes also reference the following details from the application manual:

 

 

 

VMware VCAP5-DCD : Practice Test

For every 100 users in the workload, the processing tier of the application requires one agent handler service.

Each agent handler requires one single-core CPU.

 

Which of the following should the VMware consultant do next?

 

A.

Configure the 32-vCPU box as requested and talk to the users during the rest of the project to understand the application as much as possible for ease of support and to understand the impact.

B.

Create a proof of concept server with 2 vCPUs and engage with the user/application vendor to understand actual resources required for the company workload and support requirements. Suggest other deployment strategies, such as scaling out the processing tier with a lower number of vCPUs per guest virtual machine but more virtual machines within the tier.

C.

Deny the virtual machine request and suggest that the processing tier be physical.

 

Answer: B

 

 

QUESTION 29

Application performance test cases are most accurate if based on ____________.

 

A.

quantitative success criteria

B.

vendor best practices

 

Answer: A

Explanation:The best validation is to place a platform under a typical test of what it will be faced with in the field–for example, having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary with the type of application and are primarily application functionality based. In addition, platform or infrastructure metrics are key for validation and for information to be used within the operational documentation (for example, troubleshooting guide, monitoring recommendations).

 

 

QUESTION 30

Part of your design includes updating VMware tools and virtual hardware to a newly

 

 

 

VMware VCAP5-DCD : Practice Test

updated vSphere 5.1 architecture. What is the best method for updating tools and hardware?

 

A.

Manually update each virtual machine

B.

Don’t bother updating the VMs; the new version of hardware and tools are not necessary

C.

Use Update Manager to update all the virtual machines at once

D.

Use Update Manager to help update the virtual machines in groups, as maintenance windows allow

 

Answer: D

Explanation:Using Update Manager is the best way to upgrade multiple virtu

al machines in an automated fashion. You would not want to update them all at once because it would be time-consuming and would require a lot of resources and lots of reboots. As a result, there might not be enough time to finish within a maintenance window.
